Part D Drug Event File

The PDE data contain prescription drug costs and payment data that enable CMS to make payments to the plans and otherwise administer the Part D benefit.  When a beneficiary fills a prescription under Medicare Part D, a prescription drug plan sponsor must submit a record to CMS.  The PDE data are not the same as individual drug claim transactions but are extracts using CMS-defined standard fields.
